Structure and Soft Magnetic Properties of Fe-Ti-M (M=Al,Si,Co) Ternary Films

Thickness Dependent Structure and Magnetic Properties in ⁵⁷Fe/Ti/Co Multilayers

“…The minimal intermixing in both MLs can be attributed to the small activation energy of Ti compared with other nonmagnetic elements such as Al and Si [12]. The CEMS spectra of 12 and 24TLs are shown in Figure (5). The 57 Fe layer is in contact with both Ti and Co layers and the sextets are broad with asymmetric lines with shoulders visible on the outer sides of the outer sextet lines.…”

“…A combination of excellent magnetic properties like high magnetic moment, anisotropy field, Curie temperature and permeability along with low coercivity have made magnetic, Fe/Co MLs to be studied intensively for use in high frequency inductors and read/write head applications. Factors like permeability and coercivity can be controlled by an appropriate choice of film thickness, grain size etc [1][2][3][4][5], variation of control parameters like annealing and also by using different elements for under layering [1,6]. Among the various non-magnetic elements used for under layering, it is observed that the addition of Ti has an important effect on the structure and magnetic properties in thin films like reduction of grain size, reduction of exchange interaction between grains and increasing perpendicular coercivity [7][8].…”
